Our Pneumatic Series offers the perfect combination of high quality and cost effectiveness. This desk allows you to create a great looking, completely functional adjustable desk work station at a fraction of the typical cost. Each leg of the desk has pneumatic gas springs that allow the desk to move from 29″ to 45.5″ (excluding the desktop). This enables people of all shapes and sizes to have the most ergonomic set-up. The desks feature complete stability, easy adjust-ability, and a 30 day money back guarantee. You can have confidence that these desks will meet your needs for a very long time. Our warranty attests to that promise. Assembly for these desks is a breeze and only takes minutes before you have a full functioning office workstation. (Not recommended for those who want a lot of weight on their desktops)
